The conservative firebrand is out with a fundraising message Friday attacking New Hampshire's Democratic Sen. Jeanne Shaheen for supporting President Barack Obama's quote, "amnesty" immigration policies. Cruz becomes the second Republican eying the presidency this week to criticize Shaheen on immigration. Texas Gov. Rick Perry made similar charges, which Democrats called "desperate."

The attacks come despite Shaheen's support for the same comprehensive immigration bill backed by New Hampshire Republican Sen. Kelly Ayotte.
